  • Overview

    At Rambus, we are turning incredible possibilities into everyday reality by helping to deliver the innovations that greatly impact the world we live in. We create leading-edge semiconductor and IP products, spanning memory and interfaces to security to smart sensors. Our products are integrated into tens of billions of devices and systems around the globe, running critical applications for Big Data, Internet of Things (IoT), mobile, consumer and media platforms.


    And our history runs deep – we have been in Silicon Valley for 25+ years and are continually anticipating key technology trends and are developing innovations that drive market changes. From a pure IP provider to becoming a fabless chipmaker, Rambus is evolving to address critical challenges in the semiconductor industry.


    As a dynamic organization, we are always seeking to hire exceptional talent to join some of the brightest inventors and engineers in the world to explore their passions to develop products that have real life impact. As well, Rambus benefits are among the most comprehensive and competitive in Silicon Valley.


    Rambus is looking for a highly motivated Signal Integrity Engineer working on modeling, analysis, and simulations of signal integrity (SI) and power integrity (PI) of high-speed memory interfaces.



    In this role, the engineer will be responsible for system level modeling of Packages and PCB boards. This engineer will model, simulate, correlate and optimize the SerDes and memory interfaces, will provide guideline for Chip designers, IO designers and will help with testing and debug and solves the system level problems related to the memory and serdes channels. Works cross functionally with validation, test, chip design, SI and application teams to ensure the successful tape out of the ICs, packages and PCBs.  Nice to have some understanding of DDR IO specification for DRAMs and controllers, and basic knowledge of equalizations used in SerDes like CTLE, DFE and FFE.

    • Perform 2.5D and 3D model extraction and build s-parameter models for packages and PCBs
    • Must have a strong understanding of the EM fundamentals and the EM field solvers.
    • Must know S-parameters, Smith Charts and Transmission Line theory
    • Be able to extract power delivery models for IC/PKG/BRD to help address PDN issues and optimize the system for power delivery related noise and jitter.
    • Run system simulations in ADS, HSPICE or Spectre. Understand channel simulation, transient and statistical analysis. 
    • Knowledge of source synchronous bus simulation is a big plus.


    • MS in Electrical Engineering with 8+ years of industry experience
    • Must be able to create s-parameter models from PCBs and substrates using HFSS, PowerSI and/or SIWave
    • Must know Allegro PCB layout or APD to be able to edit and optimize the design layout for extraction of electrical models.
    • Has some experience with simulation of memory interfaces and serial links like PCIe3/4
    • Experience in correlating simulation results with lab measurements.
    • Must be self-motivated, be able to manage and drive his small projects, have effective communication and presentation skills, a team player
    • Tools:
      • Must know: HFSS, PowerSI or SIWave, T-Line simulation, HSPICE or ADS,  Allegro APD/PCD layout
      • Nice to know: Totem and XcitePI


    Rambus offers an extremely competitive compensation package, which includes a strong base salary, bonus, equity, matching 401(k), employee stock purchase plan, comprehensive medical and dental benefits, time-off program and gym membership.
